swim Emile i 7 George J. M eyer, H V 1 Application March 1, 19ss,.sria1= yo. (59,159. 10 Claims. (o1."2 15 5i Y 1 This invention relates to siphon bottles, and

more particularly. to a siphon bottle having a noVelvalve and control structure.

An object of the invention is to provide a siphon head having a valve adjacent the outer end of the spout, thereby-preventing entry therein of foreign matter. Devices of the type now in use ordinarily have a spout of considerable length, open to contamination from without, with the valve located at the inner end thereof. Another object is to provide a siphon head and bottle adapted to dispense its contents without contact of the latter with metal parts or. mechanism. Other products of the type commonly have metallic mechanism within the head with ably come into contact.

Another object is to provide a valve which may be inserted in a one-piece bottle and siphon head of vitreous or non-metallic material, after the latter has been completely formed.

Another object of the invention is toprovide a siphon; head which may be constructed ,of relatively inexpensive materials. Siphon heads have heretofore. been made of pure blocktin, and are often the object of theft because of the value of the metal contained therein.

. With these and other objects in view, in}. vention consistsin the construction and combi-;

j-Fig. 1 represents a fragmentary verticaLsectional View of a siphon bottle embodying my invention p I Fig. 2 shows the device applied to a siphon,

bottle constructedof vitreous. or non-metallic material with a zinc or other simple .metal die casting encasing the head to fulcrum the, lever.

Fig. 3 shows the device applied to. a bottle formed entirely of vitreous or non-metallic material having ears raised on the head from the substance thereof in which the lever is fulcrumed.

Fig. 4 is a perspective view of the siphon head showing the manner of coupling the sleeve and lever.

Fig. 5 is a view in vertical section and Fig. 6 is an end view in elevation of the valve structure.

Referring more particularly to the drawing, in the form shown in Fig. 1, a bottle [0 is provided with a delivery or siphontube H. An exteriorly threaded split ring i 2 is placed on the neck oi the bottle Ill. The spout l3, of vitreous or nonmetallic material, enveloped .by a zinc or other metal die casting i4; threaded at I5, is turned on securely by means ofthe split ring I2.

I lever 'IG ha'Ving-a"coiled-pressure spring H partially concealedwithin the body thereof, is fulcrumed in the ears-l8; of the metal casting M. Asleeve, 20, is pivotally secured to lever i8 by means of the connecting arms 2! and the pin 22. The sleeve-2U has a reduced "opening at 23 and carries the internal washer 24 formed preferably ofarubberorfibrous material.

. Avalve stemi25 embraced atits outer end by the ring 26, is fixedly secured within the opening 23 of sleeve 20,by-means of the cross bar 21, as shown in Fig. 5. The valve stem 25 is preferably made. of stainless or corrosive resisting metal, and has an integrally formed; enlarged head 28.

A'coating-Bmof rubber or other resilient material, envelopesthe head 28. The coating or envelope 30 is. disposed on said head unequally, to the, effect. that the greater body thereof is deposited on. the seating side of the valve head, with'the inner half of the latter covered thinly as at 3| of Fig.5. The spout l3 has an opening at 32, the diameter of which is only slightly less' than the diameter of the head 28 including its envelope or coating 30. -It will readily be understood. that in assembling the-device, the valve head, because of the inequality in thickness of its envelope, may. readily be inserted into the opening at 32 of spout. l3, butwill resist all attempts to removeait without actual destruction of the said coating-30.8w I

In use,z-the bottle maybe filled in the conventionalmanner by subjecting the opening at 23 to the pressure filling-means. In this operation the "sleeve 20..is forced backwardly 'and the"wasnei- 24 is.:.brought..into.close contact with the end ofthespout l3. thereby'preventing any escape of the liquid while it is'being forced under pressureintojthe'bottle. J

After the fillinghas been completed; the pressure of spring; I l in.=the..lever I l 6 normally maintains the sleeve 20 in its extended position, in which a tension is exerted on the stem 25 to seat the valve head 28 firmly inside of spout l3 to close the opening of the latter at 32, thus preventing escape of the contents. A manual pressure downwardly of the lever l6 serves to retract the sleeve with a consequent unseating of the inner valve 28 and release of the contents.

The bottle shown in Fig. 2 is constructed of vitreous material welded to form a unitary structure. A metal casting I4 is applied to the spout [3 as a reinforcement. The manner of inserting the valve described above is the only way in which it can be placed within this form and the modification shown in Fig. 3. The latter is formed entirely of vitreous material and is minus the metal casting reinforcement. A pair of ears, l8, drawn up on the top of the spout l3, serves to fulcrum the lever I 6.

It is to be understood that the device is capable of various modifications in structure without departing from the spirit of the invention or the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States, is:

1. In a siphon head, a spout having a closure therein, a closure valve movable axially within the passage in said spout at the outer end thereof, manually operable rockable means mounted on the head, sleeve means coupling said valve and the rockable means disposed externally of said spout for effecting axial movement of said valve connecting said manually operable rockable means and said valve to operate the latter, the said sleeve means projecting beyond the outer end of said spout, a reduced portion in the outer end of the sleeve means, and an inner annular washer within the reduced portion for sealing the latter with the end of the spout.

3. In a siphon head, a spout having a reduced outlet opening, a valve movable axially in said opening and adapted to seat interiorly of said opening, manually operable rockable means mounted on the head, external sleeve means connecting said manually operable rockable means and said valve to operate the latter, the said sleeve projecting beyond the outer end of the spout, a reduced portion on the outer end of the sleeve, and an annular washer in the sleeve for sealing the latter with the outer end of the spout when the valve is open.
